University of Arizona in Tuscon researchers, led by Diego Martin, MD, PhD, chair of the university’s medical imaging department, have developed an MRI technique aimed to replace blood tests and invasive biopsies for measuring nonalcoholic fatty liver disease, according to a report by the Arizona Daily Star.

“Integration of a scoring system into structured prostate MRI reports could be of great value to clinical research as well as routine clinical care...," wrote authors of a new study published in the American Journal of Roentgenology, which examined how background signal-intensity changes affect prostate cancer detection.

The Massachusetts Institute of Technology (MIT)’s Laboratory for Computational Physiology has published their MIMIC-Chest X-Ray Database (MIMIC-CXR)—a collection of more than 350,000 chest x-rays associated with 227,943 imaging studies sourced from Beth Israel Deaconess Medical Center in Boston.

With the help of PET scans, researchers have found women’s brains appear to be three years younger than men’s. The findings, published in Proceedings of the National Academy of Sciences, may explain why women tend to remain mentally sharper longer than men.

The system, named Doctor Alzimov, after the Russian-born science fiction writer, can be installed on any computer and can find nodules as small as 2 millimeters.

In 2018, capital investments in startup companies developing medical imaging AI solutions reached almost $580 million—more than double the 2017 amount of $270 million, according to a new market report published Jan. 31 by Signify Research.

A 14-layer convolutional neural network (CNN) trained on MRI and pathology data accurately predicted the molecular subtype of breast cancers, according to a Jan. 31 study published in the Journal of Digital Imaging. The method may help personalize treatment plans for the disease.

“Applying the least burdensome approach means gathering the minimum amount of information necessary to adequately address a relevant regulatory question or issue through the most efficient manner at the right time,” according to the agency. 

At JFK Medical Center in Edison, New Jersey, patients can have a 360-degree, three-dimensional (3D) tour of the inside of their own bodies before surgery with the help of virtual reality technology at the center's Neuroscience Institute, USA Today’s MyCentralJersey.com reported on Jan. 31.

The Liberal National Government of Australia announced it is providing $375 million for 50 new MRI licenses at Medicare-eligible locations across the country, according to a recent release from the office of Greg Hunt, Australia’s Minister for Health.

“In this study, for patients with stage-IV disease, we have a treatment paradigm that can result in long-term survival while maintaining overall quality of life,” said senior author of the study, Dwight E. Heron, MD.

As the Super Bowl approaches, the NFL has announced concussions are down nearly 24 percent over the past season. This led a University of Calgary researcher to reexamine the role of medical imaging in such brain injuries.
